ROOFING-CLEAT.

Application led March 20, 1916. Seria.No. 85,282.

To all lwlw/my t may concern Be it'known that I, HARRY C. Kn'rTnLsoN, a citizen of the United States, and resident of Milwaukee. in the county of lvlilwaukee' and State of lVisconsin, have invented certain new and useful Improvements in Roofing-Cleats; and I do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in metallic cleats particularly adapted for securing roofing sheets to the roof boards of laiildings and for use in other connections wherein the cleats would be exposed to the weather.u

Various types of cleats adapted each to receive a plurality of nails for procuring a. clamping action on the roofing sheets, have been heretofore provided but these cleats have been open to serious objection in that ay rusting of the nails'is permitted. Prac' tice demonstrates that the roofing sheets will operatively ontlast two or three sets of nails in connection with the usual cleats and it has been found that water in accumulating in the rib of the cleats procures an excessive rusting of the nails.

It is therefore an important object of the present invention to provide roofing ycleats wherein the nails may be eliiciently protected against access of water to their portions within the cleats.

Roofing sheets are generally employed in connection with :more "or less temporary building structures and thus in practice an unevenness of the surface over which the rooting sheets are laid would often be encountered.

It is therefore a further object of the invention to provide a roofing cleat so formed and braced as to procure a positive clamping action only between pairs of adjacent nail receiving portions, whereby each pair of adjacent nails define an independent clamping portion to thus provide compensation for shghtunevenness of the surface on which the cleat'is secured, and further so that ifI desired the cleat may be bent.. adjacent respective nail receiving portions to extend :so`

, With the above and other objects and adaround a corner.

:vantages in view, the invention resides more 'particularly in the novel combination, ar-

rangement and formation of parte more parT Patented une ticularly hereinafter described and Aparticularly pointed out in the appended claims.

In the drawings: `Figure l is a plan view of the roofing cleat constructed in accordance with the present invention. Fig. 2 is a central longitudinal sectional view therethrough, as indicated b v the line .2 2 of Fig. 1. Fig. 3 is a transverse sectional view through one of the nail receiving portions of the cleat on the line 3-3 of Figfl. Fig. 4: is a transverse sectional view through one of the clamping portions of the cleat on the line L -fl: of Fig. 1. Fig. 5 is a sectional view'taken transversely through a modified form of nail receiving portion.

Referring now more particularly to the accompanying drawings, the cleat com- .prises'a Hat body plate 5, and struck upwardly at, longitudinal points along the plate are cup shaped projections 6 centrally apertured at 7 to receive a securing nail. In the drawings only three of these cup shaped nail receiving portions are shown althoughy it is apparent that any desired number could be employed in connection with a single cleat. Disposed between each pair of nail .receiving portions is a longitudinal rib 8 "positive clamping edge will be procured to effectivelyseal the interior of the nail cup against access of water` whereby the nail is prevented from rusting.

Fig. 3 shows, yin connection with a cross section of the cleat through a nail receiving portion, overlapping ends 9 of respective rooting sheets and a nail 10 is passed-through the cleat portion and into a roofing board l1.

The cleat plate between the brace ribs and the sides of the nail cups is not braced and consequently may be readily bent. Thus each pa1r of nails procures a somewhat independent clamping action of the rib dis posed therebetween, and thusthe rbsmay' assume diiiering relative positions within a certain restricted limit to compensate for slight variations in the'surface to which the cleats would be applied, also by the foregoing structure the cleats may be bentfat either sidej of a nail'cup to extend around a" corner, this bending being procurable without detractingrv from the clamping action of any portion of the cleat, and it is noticed that if the cleat were provided with a longitudinal brace structure throughout, such bending could not be procured without a consequent bowing of adjacent portions which would interi'ere with the clamping action.

In Fig. 5 is shown a modified form of cleat wherein the arched cross section of a plate 12 is shown and may comprise either a cup portion 6 of the plate or may comprise part of a longitudinal rib, this arched portion is provided. with a center opening 13 for receivingthe nail 14, and the material at the sides of the openingrv is bent downwardly to form a nail receiving sleeve 15, the free end of which sleeve is extended past the body7 of the plate and thus in operation bites into the roofing sheet, as shown and forms an effective seal against access of water t0 the nail.

plate provided at longitudinally spaced intervals vwith outwardly struck nail receiving cup portions and with outwardly struck ribs each disposed between a respective pair of cup portions and terminating short of said cup portions to permit transverse lexure of the plate at the sides of the cups.

2. A cleat of the type described comprising a at body plate provided at longitudinally spacedy intervals With nail receiving' cup portions having their diameters slightly less than the Vwidth of the plate to procure a clamping edge in connection with the sides of the plate, and a rib extending between each pair of respective cup portions and terminating adjacent the bases of said cup portions.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two Witnesses.
